These star trail images were taken at the Mudgee Star Party, when I was there in mid-April 2010. All images were taken with my Canon 40D sitting on a fixed tripod, with a timer remote used to program the exposures.
Time-lapse movies of these star trails will be coming in the next few weeks, once I get time to start processing them!

The image above consists of 75 minutes worth of exposure (30 second exposures), captured with the Canon 40D and 17-70mm Sigma lens @ 17mm, f/5, ISO3200. One of the domes of the Mudgee Observatory is in the foreground, with the South Celestial Pole above it.
The next image below consists of approx 1.5 hours worth of exposure (30 second exposures), captured with the Canon 40D and 17-70mm Sigma lens @ 17mm, f/5, ISO3200. The centre of the milky way galaxy rises through the left side of the image.
This image (below) is virtually the same as the one above, but totals almost 3 hours worth of exposure. All other details are the same. I just couldn’t figure out which one I liked better 🙂
The next image is a shorter star trails, of the Orion constellation setting in the West. The belt of orion and the orion nebula can be seen in the trails. It’s 35 minutes of exposure (5 minute exposures), captured with the Canon 40D and 24-105mm lens @ 24mm, f/5, ISo400.
All images processed using StarTrails.de and Photoshop CS4.
Thanks for looking.
